Ultralight and Experimental Helicopter Flight Training

In addition to the helicopter training programs, ROTOR F/X has some unique offerings you will not find at any other helicopter flight school anywhere.

Ultra-Light Helicopter Pilot - a unique program only at ROTOR F/X for ultralight builders and owners such as the Mosquito Air or XEL, 10 hours of concentrated dual "flight only" time. Although no pilot license is required for this category, professional flight training is dictated by necessity andcommon sense. Hours can count towards future ratings and is a minimum requirement from several manufacturers.

International students very welcome!

FAA Part 103 Ultralight Regulations - Experimental Helicopter Pilot - an expanded Private Pilot course for experimental helicopter builders and owners including construction, setup, rigging,tracking, balancing and operator maintenance (dual and solo time may be performed in your own helicopter subject to our inspection and approval). Course is specific to your aircraft.


For simplicity and pure "out there' flying experience consider the Mosquito Air. This is as basic and thrilling as it gets, cruising over the landscape below with little to obstruct your view or the exhilaration of the wind rushing past. This pure fun ship can be flown under FAA Part 103 ultralight rules and does not require aircraft registration or pilot license*.



When your preference in a Part 103 ultralight requires more of a standard fuselage and cockpit then the XEL will meet your needs. The integrated fuselage standard to all XE models forms a most pleasing and aerodynamic shell with all the required instrumentation and comforts a recreational pilot might want. The included safety floats provide an exemption to the standard 103 weight limit to keep this beautiful ship within the ultralight category. This helicopter can also be flown under FAA Part 103 ultralight rules and does not require aircraft registration or pilot license*.


If you have a rotorcraft rating or are planning on getting your license the XE is the place to start.
Identical to the XEL but without the floats and with an unrestricted fuel capacity the XE will really take you places. Fly for over 2 hours, or even 4 with optional extended tanks, at a comfortable cruise of 75 mph and a very economical fuel burn of only 4.5 gallons per hour. This helicopter requires FAA registration and a pilot rating with its enhanced capabilities.


Additional power is the prime feature of the XE3 helicopter. Identical to the XE in all other features, the XE3 boasts a power increase of over 30% for higher performance, a larger load or high altitude performance. You'll also experience a rated cruise speed increase to over 80 mph and a significant jump in rate of climb capability. As with the XE this helicopter requires FAA registration and a pilot rating.


his is the ultimate experience in performance, technology and pure "wow" factor. With a top speed over 100 mph and rated climb rate of 1200 feet per minute this performer will satisfy the most demanding pilot and turn heads and gather crowds wherever you travel. There is nothing like the pure power and sound of the turbine propelling your helicopter into performance parameters all others will envy. The Mosquito XET is also available ReadyBuilt© or as a full kit and can be purchased in sub groups. The turbine engine is additional on this ship and engine cost typically ranges from $10000 depending on configuration and options.
